A couple of decades ago, any question of the WT dropping or changing the blood policy was met with something along the lines of "they're in too deep, they've killed too many people, the lawsuits would kill them; they can't change it". A somewhat warped version of the "sunk costs fallacy".
They're already in very deep with the other rod for their own back, the CSA payouts. And some small changes have occurred in the way they handle CSA cases. While officially, they admit no culpability, they would rather payoff the plaintiffs than fight in court. They don't seem to have the stomach to fight against "the World" the way they once prided themselves on.
The recent Japanese articles about the legal team's survey about the abuse of children in the organisation refer to the deaths of children who refused blood at the behest of the WT. Is there a chance that interest by yet another government is going to create pressure on them in the area of blood?
